Notes on CDs
On Handling CDs
1. To keep the disc clean, handle the disc by its edge. Do not touch the surface.
2. Do not stick paper or tape on the disc.
3. Do not expose the disc to direct sunlight or heat sources such as hot air ducts, nor leave it in
a car parked in direct sunlight as there can be considerable rise in temperature inside the car.
4. Do not use any commercially available stabilizer. If you do, the disc and the player may be
damaged.

1. Before playing, clean the disc with a cleaning cloth. Wipe the disc from the center out.
2. Do not use solvents such as Benzine,
thinner, commercially available cleaners

Should I change my tubes
We are often asked if changing the vacuum tubes to a different manufacture will make the
DAC Transport sound better. We are not the politically correct source for that that type of
information. We state that the tubes of different manufacturers will make the sound different.
You will be judge whether it is better. Since the unit is extremely neutral, even subtleties of
harmonics found in the various tubes will be evident. Stating that tubes can sound different
does not answer the “what sounds better question”, but it points out a practical aspect of the
player. By using different tubes, you can craft sound in your system. For example, assume
that you have changed your speakers for another pair that are bright. By using Chinese Tubes
that have a smoother, rounder sound, you can balance that brightness out of your system.
Thus, in creating a system that has the sound elements you find desirable in sound can be
“fine tuned” through different tubes.
